The Geniuses at Apple certainly anticipated complaints about the way iOS 7 looks and how it works, but they probably never anticipated this: some iPhone and iPad users are getting motion sickness and vertigo from the new operating system.

The complaints are coming in from several Apple product forums, including the company’s official support thread. iOS 7 zooms in and out when users switch between applications and those animations may be too much for some. “The zoom animations everywhere on the new iOS 7 are literally making me nauseous and giving me a headache. It’s exactly how I used to get car sick if I tried to read in the car,” writes one user.

Why? When signals coming into the brain and the central nervous system don’t match up, such as when you’re on a ship being tossed around by waves but you don’t see the change in motion because you’re focused on stable objects that aren’t moving, you can get dizzy and nauseous. “Your brain receives messages that do not match with each other. This leads to mixed messages to the brain related to your sensation of orientation and rotational axis, and you could suffer a sense of nausea, dizziness, sense of spinning or headaches,” Dr. Robert Glatter said to Forbes.

That’s exactly what’s happening to some iPhone but in reverse — they are physically stable but their eyes sense movement in the animations that doesn’t correspond to what their bodies are feeling.

Thankfully, you don’t have to regret saying yes to the upgrade. You can make your phone less jittery by going to “Settings,” then “General” and then “Accessibility.” Click on “Reduce Motion” to turn it on. This should cut back on some of the movements that are can trigger nausea and dizziness.

I have suffered from this issue and it's also triggering migraines. The "fix" isn't available on the iPhone 4, so I've had to revert to using an old HTC Android device - I hope my carrier will provide a replacement device from a different supplier on the health-risk grounds.

Fact is, far more than 90 percent of the current owners of iOS devices have chosen and bought their products with iOS-versions BELOW 7. All these versions were quite similar in usability and design.

These users have chosen and bought their devices BECAUSE of the approved and well known iPhone look and feel BELOW Version 7.

Up to now, these users are used to frequent improvements to the iOS which formerly extended the functionality, usability and the security of iOS. These users did not at any time expect any major changes in design nor in usability.

But what did Apple do now?

If users do not like the new design - and users have the right to choose because they paid a lot of money for the devices - these users are cut off from all future improvements and from all future security updates.

So, for me it's like a kick in the ass of the customers who made Apple what it is now: The nearly biggest player in the Mobile Phone Market.

Please, please, you all in the Board of Directors at Apple: Think about it! Take care of your customers!

That accessibility option only turns off parallax motion (the slight movement of a background as the orientation of the phone changes). It doesn't have any impact on any of the triggers described in this article as possibly causing motion sickness.

My daughter whom is 21 has been complaining for almost 2 weeks or being dizzy, nauseated and just plain feeling like crap. She started getting really worried when she started having panic/anxiety attacks which landed her in the ER. (she had never suffered from them before) She went to her regular doctor whom thought it was sinus pressure or maybe ears, put her on antibiotics but it never got better. She saw a post today on FB about this exact problem. She turned her phone off and didnt use it almost all day and the symptoms subsided. What sucks is the FIX doesn't work and she can't delete IOS7 because it is past the deletion time line. She had to file a complaint with Apple.

I WAS going to get a new iphone 5s to replace a stolen phone. But now I am going to rethink that. I too suffer nausea from things. ( I almost hrew up during Avatar 3-d)

IF Apple cannot make software that does not make me nauseated, then for the first time since 1989, I will turn away from this company. And that is sad, because I have always appreciated their comment to their customers

But if Jonathan Ive's beloved belief that appearance is superior to comfort/ ease of use, or consumer preference, he is mistaken. I fear it will take a class action lawsuit to fix this. Apple's silence on this issue is curious and surprising

I'm housebound with severe ME and so the internet is a lifeline for me in terms of contact with the outside world. Ever since I installed iOs7 on my ipad I have been feeling motion sick, like I am on a boat. It is hard to walk in a straight line. It is particularly bad when I stand up and try to walk.

This is more than just an umcomfortable feeling - this is making me ill. I have done the adjustments suggested - the reduce motion settings etc but it does not make a difference. Apple have failed many disabled and already-sick people, and I hope that they are going to fix this. I am disappointed by the attitude of some people in various comments, saying that sick and disabled people should stop complaining about iOs 7 because it doesn't affect the majority. Apparently it is very difficult to uninstall iOs7 and it is a shame to exclude so many people from the new software. This is 'cool animation' versus 'making sick people sicker'. Apple need to do the right thing here.

@goblue562@BillJohnson Thanks, I am humbled by your comment. I write for a school newspaper. Perhaps I will be able to write for "Time", someday. Alexandra Sifferlin is a writer and producer for TIME Healthland. She is a graduate from the Northwestern University Medill School of Journalism.

@BillJohnson@goblue562 Note: When citing or referencing a repeating publication such as Time, you should italicize or (though now more or less defunct due to hyperlinking protocols) underline the name. "Quotation marks" are reserved (when not directly quoting, of course) for articles with a given publication, such as, "iOS7 Making You Dizzy? Here’s Why–And a Fix".

@CthulhuShrugged@BillJohnson@goblue562 Acutally, journalistic style (e.g. writing for a newspaper) doesn't normally use italic type. It's a tradition that stated back in the Linotype era (if not before) in the interest of getting the type set as quickly as possible. Bill is correctly using the style he learned for his school newspaper: quotes around titles of books, magazines, and scholarly journals.

@stonecutter0602 I am a former Blackberry user who has used an Iphone 5 with IOS 6 for over a year and now has upgraded to IOS 7. This operating system is fantastic. It is smooth. I have never had a screen lock. The zooming movement on the screen have never made me dizzy, and I actually like the dynamicity of it. The new graphics are truly elegant, and the shortcuts to the light app, the music app, the screen dimmer app as well the new global search feature make life so much simpler. I love the way that holding the home key on my Iphone allows me to take multiple photos of the same scene with different light settings. Just last week, I was taking pictures of wild horses in a Western state at sunset, and thought that for sure these photos were going to be too dark. The multiple photos feature in IOS 7 adjusted for the low light in my photos, and i was totally delighted.

This is the best version of IOS released to date. Thank you Apple. I will never go back to the near defunct blackberry. Apple makes the most user friendly yet sophisticated smartphones in the business. Thank you.

IOS7 is a stone mess, and that's using polite language. Today, for no apparent reason, after I downloaded the software 2 days ago, my screen started going haywire right in front of me, zooming in so much that the clock icon took up the whole screen! Nothing worked correctly, and for 20 minutes I couldn't get the phone to properly switch apps or return to the home screen. It went completely crazy, but then all of a sudden, just when I thought I'd have to get in my car and drive to the ATT store, it returned to "normal". How long it remains that way remains to be seen, but so far, so good. Plus the new graphics suck, the screen transitions are not nearly as smooth as they were before, and I'm very sorry I downloaded this new software. Apple has gone rotten.

This article is wrong. Reduce Motion has nothing to do with the zoom effects or other OS animations. It ONLY turns off the slight 3D effect of the wallpaper. There is no way to disable the new Windows Phone-like zoom effects unfortunately.

@peter_yogi@peter_yogi There is NOT a mandatory data plan for smartphones. Only if you get "subsidized pricing." They make that $450 back through data plans. Just buy the phone outright and you can do whatever plan you want.

@russfr@peter_yogi That's not quite true. You can buy an unlocked phone and then use whatever plan you want. However, if you do use any data (even if you are not on a data plan), AT&T will detect your smart phone and then put you on a mandatory data plan. Yes - if you use a smart phone - AT&T will require that you have a data plan, even if you don't want or use data.

This is beyond absurd. My wife gets motion sick if she see water in a glass moving and yet she has no problem with the IOS 7 motion that people seem to be complaining about. Why is that? Maybe it is not really a problem but a bandwagon thing. Someone says people could get motion sick from the IOS 7 UI and all of a sudden people start feeling motion sick. I think the problem exists more in people's heads than on any phone.

@brenro12 Now, now. Be nice. Keep in mind the average iUser has never had to produce much of anything besides pretty pictures and photos of their junk (for eBay, of course). One must be patient and see if they work up to anything useful as they grow up.
